The triangular navigation protractor with a gripping strip helps you to measure angles exactly. Against a white background, the angles are depicted in two different colours (blue: 0° – 180°, red: 180° – 360°). To facilitate reading the true course, the triangular navigation protractor bears a blue and a red aircraft symbol besides the degrees in blue and red.
